anyone have a recommendation for a thread plate to test the types of little tiny screws that tests English and metric sizes.

i'm converting dc locomotives to dcc and have discovered that metal screws in locomotives are often the source of evil electrical decoder killing shorts and that i should get nylon ones, but i need to know the size of what i'm getting. :(

Something like these: https://www.mcmaster.com/#98728a112/=16o5dz6 and https://www.mcmaster.com/#98728a114/=16o5e6g

I would make my own using nuts or standoffs, and epoxy them to a board.
